KYB PSF 1 Air Fork Tech Specs

• Pressurized air replaces main spring and pressure spring decreasing weight and friction
• A change of 2 PSI is similar to 1 spring rate change such as .44kg/mm to .46kg/mm
• 33psi target weight range is 170-190lbs
• Balance spring is 3.2N (Click here for other balance spring rates)
• Midvalve piston diameter increased to 32mm (same diameter as compression piston)
• 2013 midvalve piston is previous KYB two port and two piece design
• 2014 midvalve piston is new KYB three port one piece design
• Both midvalve pistons have large bleed holes and float amount
• Larger diameter bottoming cone for improved bottoming control
• 2 pounds lighter than previous spring forks
• Lower Tube OD: 48mm
• Fork Adjustments
• Compression: 22 clicks
• Rebound: 20 clicks
• Air Pressure: 30-42psi
• Fork Oil Volume: 190-265cc
• Fork Inner Cartridge Oil Volume: 343cc (5wt)
• This fork is similar to the KYB A-Kit Air Fork

KYB PSF 1 Air Fork Tips

• Best to use genuine KYB or SKF air fork seals
• Check air pressure before each ride
• Out chamber fork oil volume can be adjusted to manipulate fork pressure progression
• Replace fork cartridge seals every 60 hours
